Chemical Engineering in Daily Life – Question 39: On an airplane, if you feel cold, would you use a small blanket to cover your upper body or your lower body?
Thread Content
On domestic flights, it’s a common sight: a rather burly and overweight man who, as soon as he gets on the plane, starts complaining about the cold and asks the flight attendant for a blanket. I think his heart is cold. There are countless ways to cover a blanket. However, due to the limited thickness and size of the blanket, it cannot cover the feet. So the question boils down to whether to cover the upper body or the lower body. May I ask, if indeed your clothing and the temperature in the cabin make you feel extremely cold, and you’re wearing the same amount of clothing on top and bottom (for example, pants), how can you use a small blanket to feel warmer after a while? Or rather, to avoid catching a cold from the cold? 1. Wrap your head up ； 2. Use a blanket as a scarf to wrap around the neck ； 3. Cover the shoulders, chest, and belly ； 4. Cover the legs ； 5. Wrap your feet up.
From a medical perspective, it should be 5 or 4. But this depends on the aircraft’s ventilation and air supply system
Cold starts in the feet, but the head also loses heat quickly. The feet are at the extremities; when they feel cold, it means the temperature there is low. Reducing heat loss from the feet helps
To warm someone, start by warming their feet. Wrap your feet up.
In most cases, according to the quantitative analysis results from chemical engineering, a considerable number of \"common sayings\" are incorrect.
3. Cover the shoulders, chest, and belly；
3. It’s not easy to get sick from getting cold in other areas, but getting cold in these areas can easily cause stomach pain!
Protection starts with protecting the heart; the head has a high degree of adaptability, but once the heart cools down, everything else does as well.
It must be covering the lower body; since the lower body is farther from the heart, it naturally needs to be thicker.
It varies from person to person; choices differ. Stay normal, or take good care of your abdomen as well as your shoulders and knees that are prone to getting cold
